IMPROVED CULTIVATOR.

The Schedule referred to in these Letters Patent and making part of th'e same.

' To all whom it may concern.

` B e it known that I, Moses JOHNSON, of lhree Rivers, in the county of St. Joseph and State of'Michigan, have invented a new and valuable Improvement neference marked thereomj. u

tion.

Figure 2 is aeentral vertical section. lFigure 3 is a detailed view.' My invention relates to cult-ivatois, and consists in certain improvements upon the cnltivator part ot' my Figure 1 of the drawing is a top view oi'lny inven- =A of the drawing represent-s the beam of my im# proved cultivat or;

1%,.the main handlesgjaud Q,7he main beamf cr cross-bar.

'lo the cross-bar C I arrange staples, D, in. which iI arrange the. concave disks E, in such. manner that their concave sides shall be turned outward, and they 'lieuallowed to rotate on suitable bearings. u

I also arrange scrapers,`a, on the concave sides of these disks. I also make the position ot' these disks iadjustable'by means of apertures through the bar G, through which apertures, respectively, I pass the heads of staples I), and make said staples removable by means of the threads and nuts that hold them upon Ilhe apertures above mentioued'are marked c on the Idrawinof. By adjust-ing the heads ot` staples D in the strong wires or strong-steel bars, bent into the shapel represented. The are suiciently strong to serve as meausfor pulling lpand removing weeds .andorgli nary obstructions, but still are not too rigid to s erve as springs, and pass over bowlders and the like, without .stopping the forward movement of the cultivator. fflo the front end of the beamA I attach a brace or le'ver, K, perforated, as shown, and connect said brace both to said beam and the draw-bar N by means oi' pivot pins.

.The draw-bar N is pivoted at its rear end to the plow-beam, and atkits front end to the brace K, in the manner shown, and the distance of its front end from theplow-beam `is regu-lated, at will, by means of the apertures-c in thc brace, and' the pivot-pin hy which said brace is united with said plow-beam.

l represents an auxiliary and movable p low-haiulle,

.connectedwith the beam and handles in the manner ashown on tig. l. combined potato-digger and cultivator patented August 3, 1869,' by which said device is intended to be made more generally useful and effective.

`The object secured .by -thc brace K, draw-bar N, and auxiliary handle l) is as follows, namely:

\Vhenever it is found desirable to straddle a row of plants with thecultivator, and thereby 'cultivate more closely to the hills, I attach thcanimal or auimalsby which it is moved to the end ot the 'draw-bar N, and guide the cultivator hy means ot' the auxilary handle l and the cultivator-handle next adjoining.v

In order to overcome the ditliculty ot' moving the cult-ivator in a straight liuc, when the/line of draft is t transferred from theend ofthe plow-beam' to the draavfbarN, I arrange theplowiug-disks in such man- I 11er that the left-hand disk shall be adjusted at a more acute angle than its fellow,` and thereby create a greater power of resistance, -by plowing a broader furrow.

IVhat I claim as III-y1 invention, and desire to secure by Letters Patent, is- 1 The cultivator herein described, having cross-bar G,.staples D, disks E, Scrapers a and H., brace 1i, draw-bar N, and auxiliary handle I), when constructed i and arranged to operateasaud for thepurposes specified, as an improvement upon my patent of August 3, 1869.

'In testimony-that I. claim the above,` I have 'hercunto subscribed my name' in the presence ot two witnesses.

MOSES JOHNSON.
